### <samp>🤖[[deprecated]](https://githubnext.com/copilot-for-prs-sunset) Generated by Copilot at cdd012c</samp>
This pull request refactors and enhances the update functionality for the frontend. It introduces a new custom hook `useAppUpdater` that simplifies the update logic and state management, and uses it in various components and commands. It also adds more options and feedback for the user to control and monitor the update process, such as manual download, auto-check, and auto-download toggles, and update status and progress indicators. It also updates the `AboutAffine` component to show the app icon, version, and build type. It also adds new translations, dependencies, types, and schemas related to the update functionality.
